I tried CafePress a while back, and they would only let you put a single design on a single product. Zazzle makes it easy to do bulk product setups. Got single image? Put it on everything in one shot. Why would you want to restrict people from order more of your product? CafePress' system doesn't make any sense.
Oh, so what am I selling?
